He spent almost a month at Inova Fairfax Hospital before he was let out on Monday. NBC News confirmed reports of his release Monday afternoon.

Cheney returns home with a new pump in his ticker -- more specifically, a left ventricular assist device (LVAD) that was installed in early July to help his damaged heart. His hospitalization for the surgery was kept under wraps for about a week before the press got word that he was admitted to Fairfax Inova.

Cheney, 69, has been suffering from heart attacks for decades and said the LVAD was to remedy his new phase of worsening cardiovascular disease.
